Lion Creek and Lower Raypits is a 65.2-hectare (161-acre) nature reserve east of Canewdon in Essex.

It is part of the Crouch and Roach Estuaries Site of Special Scientific Interest,[1][2] and is owned and managed by the Essex Wildlife Trust.

[3] The former creek has been cut off from the Crouch Estuary by a seawall, and it has salt marsh plants such as golden samphire and sea-spurrey.

Lower Raypits can be accessed from Lion Creek by the seawall path.

It has a variety of pasture, salt marsh and intertidal habitats, with nationally scarce plants such as beaked tasselweed, sea barley, grass vetchling and curved hard-grass.
